THOMAS J. ADAMS, OF JUNIATA, NEBRASKA.

WATER-ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 225,909, dated March 30, 1880.

Application filed April 21, 1879.

To all whom it may concern:

Be it known that I, THOMAS J. ADAMS, of Juniata, in the county of Adams and State of Nebraska, have invented certain new and use ful Improvements in Water-Elevators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to water-elevators; and the novelty consists in the construction and arrangement of parts, as will be hereinafter set forth, and pointed out in the claims.

The annexed drawings, to which reference is made, fully illustrate my invention, in which- Figure 1 represents a front view of my improved water-elevator. Figs. 2 and 3 represent side views of the same. Fig. 4 represents a front View. Fig. 5 represents a vertical sectional view. Fig. 6 is also a view; Fig. 7, a vertical section; Fig. 8, a side view of the winding-drum; and Figs. 9, 10, 11, and 12 are detail views of the same.

Referring to the drawings, A designates the frame-work, in which is journaled a drum provided with the box or hearing a, in which the shaft to of the drum revolves.

B indicates a winding-drum having holdingflanges I) b and an internal-gear wheel, I), revolving loosely on the shaft a.

(),is a pinion keyed to the shaft a within the windingdrum B, and gears with a cogwheel, 0, which is interposed between said pinion 0 and the internal-gear wheel I). Said cog-wheel c revolves freely on a stud or small shaft, 0, which passes through a perforation near the center of a lever, D, that is provided at one end with a tooth, d, to engage with the cogs of the pinion O, the opposite end d of which engages with an elbow-arm, E.

F is a second lever, perforated at one end to receive the shaft to, and connected to lever D by means of the shaft 0 passing through the perforation in said lever. The levers D and F are provided with a spring, 01 for the purpose of keeping the tooth d in engagement with the teeth of the pinion O.

L is a latch, pivoted at one end, at f, to the side of the flange b and provided with a tooth, f and apin,f Said pin passes through a slot, f, in the flange b and lies within a groove or slot, f, on the periphery of the winding-drum B. The tooth aforesaid remains within the slot in the periphery of the drum B when the rope of an elevator-bucket is being raised by means of said rope winding on the drum B and over the pin f.

E is a curved arm, pivoted at c to the windwheel frame A, a portion of which arm is bent at right angles to the same, and curves downwardly, as at e, and has a curved arm, a, the end 6 of which is pivoted at c to the frame A of the wind wheel. A lug, 0 engages the tooth f on the latch L aforesaid.

G is a rod provided with a hook, g, that passes under the curved arm 6, for raising the same when the lower end, g, is struck by the ball 9 on a rope attached to an elevatorbucket. Said end g of the rod G has an eye in the same, through which said rope passes.

Operation: The operation of my improved water-elevator is as follows: Motion is communicated to the winding-drum B by means of the cog-wheel c, interposed between the internal-gear wheel I) and the pinion O on the shaft a of the wind-wheel. When the latter (the wind-wheel) revolves the pinion O revolves therewith, thereby winding the rope upon the drum B between the flanges b I) and over the pin f, which causes latch L to remain within the notch within the periphery of the drum B. At the same time the lever D rest-s 011 the arm E of the tripping device, thus withdrawing the tooth d of the lever D from engagement with the cogs of the pinion G, permitting the latter to turn cog-wheel 0, internal-gear wheel I), and drum B in winding up the elevatorrope. This movement is continued until the ball g on said rope is sufficiently raised to come in contact with the lower end, 9', of the rod G, after which the rod G is raised, and forces the curved arm 0 upwardly, which has the eifect of thrusting the arm E, which turns 011 the pivot at e, from beneath the lever D, releasing said lever and allowing the drum B to revolve reversely and, the rope and bucket to descend and re-enter the well.

When the rope is unwound from the drum B, the end attached to the drum at m prevents said rope from becoming disengaged from the drum, and the pivoted latch L, after being released by the rope unwinding from over the pin f allows said latch L to drop and the tooth f to engage with the lug e on the curved arm of the tripping device aforesaid, after which the levers D and F move around the entire circle of the drum B by means of the pinion 0, keyed to the shaft a and revolving therewith, thus communicating motion to the cog-wheel 0, and at the same time the drum B and its internal-gear wheel I) remain motionless until the end d of the lever D strikes upon and rests on the arm E, thereby causing the cog-wheel e to'act upon the internalgear wheel b and revolve the winding-drum in an opposite direction to the revolution of the shaft a of the wind-wheel, as shown in Fig. l of the drawings. The rope is then wound upon the drum B and over the pivoted latch L, thus elevating the bucket, when the same operation is repeated as the wind wheel revolves.

The windingdrum B is also constructed with the flange Z2 and the groove in which the rope is wound on the drum B to one side of said drum; and opposite the b is a loose pulley, N, on a hub, 12, on the drum B, for the purpose of receiving the surplus rope by which the elevator-bucket is raised and lowered. A pin, a, is then inserted through the drum- B and into the pulley N, thereby keeping the latter fixed to the drum B, that the same may revolve therewith; also, the latch is pivoted within the groove of the winding-drum, and the pin 0 projects through the slot in the flange Z1 and engages (when the rope is unwound from the drum B) with an arm, 0, pivoted to the frame A of the windwheel. Arm 0 is connected at its upper end by a chain or other fastening to the arm 0 and causes the latter to be drawn forward and in engagement with the end (1 of the lever D. Arm 0 is pivoted at its lower end to the frame A. The rod G is pivoted to the arm 0 at its upper end, to throw the arm 0 out of engagement with the end cl of the lever D, thus allowing the drum B to revolve and unwind the rope of an elevator-bucket. The arm 0 is also constructed with a bend, P, in which one end of the connecting-chain aforesaid is attached. Such construction causes the arms 0 and 0 to be out of engagement and not in the same vertical plane with one another.

It will thus be seen by the foregoing description that when an elevator-bucket is descending into a well the gravity of the same causes the winding-drum to revolve with the shaft, restrained by tooth d on lever D, and thus the speed of said bucket in descending is regulated by the revolution of the windwheel.

. t will also be observed that should the rope or other parts become disarranged the winding-drum will remain motionless while the Wind-wheel, with its shaft and pinion, is revolving, thus carrying the cog-wheel c and the levers D and F therewith. The clicking of the tooth (Z on. the lever D, in en gagement with cogs of the pinion 0,

gives warning of such internal-gear wheel dis'arrangement of the various parts liable to the same.

I do not wish to confine myself to the exact construction of my improved water-elevator, as various changes could be made in its construction and ofthe tripping device without departing from the spirit of my invention. The shaft a and drum B may be mounted above the frameA and the rope guided to the proper place over a roller or pulley, or power maybe transmitted from a wind wheel by means of gearing or belts, shafts, 850., to any suitable place formounting the winding-drumB and the wheel and shaft that drives it. The lever D may turn loosely on the shaft to and engage with the cogs of the wheel 0, for preventing the relative revolution of the cogs and gearwheel while the bucket is descending into the well, and a block may be interposed between the internalgear wheel 6 and the cog-wheel 0, or both; also, a ratchet-wheel may be applied to or a part of the pinion 0, upon which may operate the tooth d on the lever D.

It will be understood that the speed of the winding-drum B will be less than. that of the wind-wheel shaft to, or inversely, as the number of the teeth in the wheel 0 and b, the power of the machine increasing as the rela tive difference in the number said wheels.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The levers D and F, having spring (P, in combination with the drum and the arm E, substantially as described.

2. The drum B, latch L, having tooth f and pin f in combination with the elbow-arm E, provided with lug 0 substantially as described.

The combination of the drum B 1) D internal gear, I), pinions O 0,1ateh L, elbow-arm E, guide G g, and elevating-rope, as and for the purposes set forth.

4:- The combination of the winding-drum B, having the internal gear, I), pinion O, keyed to the shaft a, cog-wheel 0, levers D and F, having spring (1 latch L, pivoted to the drumv B, and arm E, substantially as described, and for the purposes set forth.

5. The winding drum B, mounted on the shaft to of a wind-wheel and on one side of the vertical frame A, 011 which the wheel revolves, substantially as described, and for the purpose set forth.

6. The lever D, having arm d and spring (Z in combination with the winding-drum B, provided with the pulley N on the hub n, for receiving the surplus rope, substantially as described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 25th day of March, 1879.

THOMAS J. ADAMS.
